    I am attempting to replace a Lasko box fan 3 speed rotary switch. I was wondering if anyone could help me determine: a) if this switch has the same capabilities as the original, and b) how to wire it up.

    I am confused because the replacement switch only has 4 input terminals, while the original has 6. If I need to include a 120v on/off switch into the circuit I have the switch already, and would like wiring instructions, too. Thank you!

    The replacement switch pictured below has 2 terminals on each side:

    Is this diagram correct if I use my own on/off switch?

    The neutral is just a thru on the original switch. Your schematic is correct, except the on-off switch is probably not needed. Check the new switch to see if there are 4 positions. If so, one of them is "OFF".

    How annoying, after all of that work it wasn't the switch that was bad. It must be the motor, or some other component I am not familiar with. I tested the new switch and it was doing its job. I might as well spend the $30 on a new one.

    I never included this info but I found this fan in the trash and thought I could bring it back to life. The motor wasn't seized up so I assumed it was good.
